require-skip-cache

Require a module without adding it to the cached modules

Why?

You probably don't have a use for it, but I use it to dynamically create sandboxes for Node's vm module.

Usage

var _require = require('require-skip-cache')
var request = _require('request') // will not be added to Module._cache

request('http://google.com/', function (err, res, body) {
  ...
})
